La plastica è quasi ovunque non solo negli imballaggi. Svariati tipi di polimeri sono usati ad esempio nell’abbigliamento, nei trasporti, nell’edilizia o nella medicina. Grazie alle sue straordinarie qualità e al suo basso costo, questo materiale ha segnato lo sviluppo economico del dopoguerra contribuendo alla diffusione di svariati beni di consumo. Il suo successo ha portato però anche a seri problemi di inquinamento ed ora si cerca di limitarne l’uso, promuovendo il riciclaggio, in realtà poco diffuso in Svizzera, nonché l’uso di materiali alternativi di origine non fossile. Ma le bioplastiche sono sufficientemente attrattive per le aziende? Perché il Pet riciclato è più costoso di quello nuovo? Quali materiali ci accompagneranno in futuro?
